APPARATUS FOR TREATING EMULSIFIED' OII.

Application 'led October 21, 1920, Suerial' No. 418,566. Renewed March 24, 1927.

rThis invention relates to apparatus for' treating emulsiied oil and refers more particularly to the dehydration of emulsified petroleum oils such as California or Mexican crude petroleums, bottom settlings or the like.

The object of the invention is to cause the breaking down of the emulsion by mechanical means and more specifically by causing 310 the oil to pass through a series of small orifices under a predetermined pressure. The oil may be treated cold, although as a modification of the invention,wthe oil may be heated if desired, to any given temperature l5 short of vaporization.

Referring in detail to the drawings, 1 designates as a Wholethe treating chamber, provided with an inlet suction pipe 2, leading to the valve chamber 2n. 3 designates the spring valve members and 4 the suction chamber. In the main chamber 1 is mounted a piston 5, having piston rod 5 extending out through stuiiing box 5; This piston is provided with a series of spaced, circumfen entially extending ducts 6, which are small orifices of predetermined size and open at either end. At the rear end of thepiston head, these ducts are controlled by the ball valves 7 mounted in the valve chambers or valve caps 7. The arrangement is such that as the piston travels forward, the ball valves are unseated and the emulsilied oil forced under pressure through the ducts 6. As the piston returns, the ball valves are closed and the oil in which the emulsion has now been broken down, forced out into the discharge chamber 8 and thence through the valves 9 where the oil and Water Will separate by gravity.

Fig. 2 is a cross sectional view taken on' As the piston moves on its return stroke, 1t forms a suction at the front end of the cylinder and emulsified oil is drawn in through the valves 3.. It will thus be seen that the piston simultaneously draws in emulsiied oil on one side of the piston and discharges the de-emulsified oil on the other side of the piston. On the forward stroke of the piston, the oil already in the front end of the treating chamber or cylinder is forced under pressure through the orifices Gand as the oil is forced tofpass through theselvery fine openings, the emulsion will be broken down. The size of the openings will depend upon the degree ofemulsification; with oils that are very badly emulsied and in which it is diicult to break the emulsion, very fine ducts may be necessary. It is also to be understood that the number of these ducts.

is provided with an extension 5a and the stroke of this piston rod or piston can be shortened or lengthened by means of the device 11, which can be moved along and set at any desired position on the rod 12. On the piston rod is fixedly secured a' crosshead 13, which is adapted to strike the pins 11 upon the reciprocation of the extension 5% The crosshead as it strikes the pins 11 actuates the pivoted member 14, which is secured to the rod 12. This pivot member in t'urnis arranged to shift the belts l5 and 16,'so as to reverse the direction of movement of the piston as will hereinafter more clearly appear.' In the drawing, the belt 15 is running on the loose shaft 17. When the cross head comes in Contact with the pins 11, the

lbelt is shifted over to the pulley 18, which leys on the shaft 17 are idlers and that the belts are shifted alternately to the Xed pul` ley, so as to properly reciprocate the piston. The cross head 13 moves in the rectangular guide frame 21 as shown clearly in the drawings. The manner of actuatingl the driving mechanism should be apparent from the foregoing description and need not be def4 said inlet and outlet, a plurality' of restricted passageways, extending through said piston,

means for reciprocating the `piston under pressure to'force emulsiied oil through said passageways, means 'for preventing the return of such oil through said passageways when the piston is reciprocated to eject 4the de-elnulsied oil.
